Formula 1 teams will be allowed to use their latest-spec cars at demonstrations organized by the sport from 2018, the FIA has confirmed.

F1 hit the streets of London, England ahead of the British Grand Prix in July for a live demonstration that attracted a crowd of over 100,000 fans.

Due to restrictions on the use of current cars outside of official testing and grand prix weekends, all teams were required to appear with older chassis models in London, most coming from 2015, the most recent year allowed to be used freely.

The restrictions meant that Haas, which only became an F1 team in 2016, could not field a car at all in London.

As part of the updated sporting regulations approved by the World Motor Sport Council and issued by the FIA earlier this week, a rule tweak was confirmed to let teams use their current-year cars at “demonstration events organized by the Commercial Rights Holder”.

Teams are still allowed to complete two filming day events with their current cars, with the majority opting to use one prior to pre-season testing to act as a shakedown of their new models.

While no further demonstrations such as the one in London have been confirmed by F1 yet, they are understood to be in the works after the success the July event enjoyed.

Are you expecting a better than normal tax refund? Did you get a very nice bonus from your company due to the new tax cut?

Well, if you have a good chunk of change hanging around and potentially can be in Monaco on May 11, you can have a chance to bid on the 1993 McLaren-Ford MP4/8A that the late Ayrton Senna drove in — and won — that year’s Monaco Grand Prix.

We’re not just talking about any race winner. It’s also the same car Senna won his sixth Monaco Grand Prix, and the chassis bears the number six.

It’s also the same car Senna piloted to that season’s F1 championship (his third and final title before sadly being killed the next year) and is the first McLaren driven by Senna that’s ever been sold or put up for auction.

The famed Bonhams auction house is overseeing the sale of the car.

“Any Grand Prix-winning car is important, but to have the golden combination of both Senna and Monaco is a seriously rare privilege indeed,” Bonhams global head of motorsport, Mark Osborne, told The Robb Report.

“Senna and Monaco are historically intertwined, and this car represents the culmination of his achievements at the Monegasque track. This is one of the most significant Grand Prix cars ever to appear at auction, and is certainly the most significant Grand Prix car to be offered since the Fangio Mercedes-Benz W196R, which sold for a world record at auction.”
